Widescreen With some help i have my N100 now running perfect (for what i do). I needed to patch the kernel to workaround that problem.

If you want to use LE a patched image is here https://sky42.libreelec.tv/release/11.0/G…/Generic-ADL10/.

Any other Linux distro has most likely the same that you can read here Intel Alder Lake 2160p @ 23.976 Hz passthrough HD Audio dropouts (i7-1270p/N100).

Kodi did break MySQL more then one time with the update 21b2 ff.

I rolled my community build back to a version that works for me. Any of my 240109 should do but not 240110.

Or better use LE11 if you don't need 12.

Works perfect here with 11.0.4.

Yup kind of the same here with RPi2 (not anymore), RPi4, RPi5, i3-8100, Vero 4k+ and very new Intel N100 all connected to X6700H to LG 55E6D. It is not the Pis it is Denon i fear. Intel is slightly less annoying . The X4500H before was not much better. I have all HDMI CEC off. The RPis and Denon do not really like each other. So far I did not find anything, but I leaned from you guys Denon Input switch helps. Did not know or try that before. Thanks.

So now i established my new baseline where i can reproduce a working and a non working version with LE11 and LE12

LE11 11.0.4-#240109 https://sky42.libreelec.tv/release/11.0/G…/Generic-ADL10/
- Generic-ADL10 is working perfect for me with Intel N100
- Generic-BT2020 is the counterpart without the 10 bit patch as the only difference
- tested 1 movie 1st BT2020 after 3x (about 5mnin) audio glitches switch to ADL10 and the rest was flawless
- sources https://github.com/sky42src/LibreELEC.tv/tree/11.0.4-240109

LE12 11.80.5-#240109 https://sky42.libreelec.tv/testing/12.0/G…/Generic-ADL10/
(i would not use LE12, because kodi + mysql is at the moment very wonky and OS nfs4 is broken too)
- 2x downgrades in my 11.80.5-#240109 release to get mysql and OS nfs4 working
- Generic-ADL10 is working perfect for me with Intel N100
- Generic is the counterpart without the 10 bit patch as the only difference
- tested 1 movie 1st Generic after 3x (about 3min) audio glitches switch to ADL10 and the rest was flawless

Heads up cifs/nfs4 OS mounts broken in my ADL10 images. Kodi still can do smb/nfs directly.

chewitt I see your point, doing that is not my forte. The kernel hack is very specific to the GPU generation and i am not sure one could do that in kodi too.

here is a new Generic device with a patch of smp that restrict playback to 10 bit on Intel 12th CPUs and later and in doing so HD Audio playback is perfect in 2160p @ 23.976 Hz and UHD BD works still too with HDR.

https://sky42.libreelec.tv/release/11.0/G…/Generic-ADL10/

Not yet well tested, but it works for me (the last 90min) in solving ONLY the problem of this thread without using one of the 2 workarounds i described here (so remove them when you use this image).

jordiboy I have a Intel N100 HUNSN BM34 too that is lets say interesting, that one i will send back. A bit cheaper as my ASUS PN42, but the ASUS PN42 is the perfect LE x86_64 box in my opinion. Hopefully this 3rd workaround fixes my last Problem.

smp thank you so much! I will build LE11 and LE12 images next week (today family party)

verified 4k HDR playback UHD BD remux TrueHD Atmos played perfect too in a 30min test

verified autostart.sh workaround activation and uploaded my autostart.sh to https://sky42.libreelec.tv/testing/proptest/

smp you are the man: forcing 8 or 10 bit both fixes the problem. What impact has it to only use 10 bit instead of 12?

Forced 8 bit test 30min and 10 bit 60min without a audio glitch playing 1080p BD remux TrueHD Atmos at 2160p with 23.976 Hz with audio pass through.
Tested with my LE 11.0.4-#231221 Generic-BT2020 on my ASUS PN42. Most likely any LE11 or LE12 will be fixed by that.

new workaround
- download proptest for LE11 or LE12 https://sky42.libreelec.tv/testing/proptest/
- make it executable (and rename if you like)
- run it and find out your active Connector number
- systemctl stop kodi && ./proptest <your number> connector 191 10 && systemctl start kodi
- dont forget to enable 3840x2160 @ 23.976 Hz in you whitelist

A more convenient way of doing that would be put proptest <your number> connector 191 10 in autostart.sh

I will test some more.

Has anybody any pointers where i could open a bug for that? Intel media driver, linux kernel or Intel guys who maintain the linux parts for Intel. I am not sure what software part ist responsible for that problem, so i dont know where to open the bug.

w46n3r your hint was very helpful and works for me too (at least the fist 10min)
RE: HDR on x86 Hardware

Just disabling 2160p @ 23.976 Hz and play it at 2160p @ 24 Hz fixes the audio problem and HD audio pass though still works despite the not matching frame rate / refresh rate.
Workaround settings LE11:
System -> System -> Display
- Resolution 3840x2160
- Refresh 24 Hz
- GUI resolution limit 1080
- Whitelist what you want BUT without 3840x2160 23.976 Hz
for me that is 3840x2160 in 60, 59.94, 50, 30, 29.97, 25, 24
System -> Player -> Videos
- Adjust display refresh rate On Start / Stop

What does it do? If kodi does not find a matching refresh rate in the whitelist it plays in the screen resolution / refresh rate that is on right at starting playback. We set screen resolution to 3840x2160 with 24 Hz and change refresh on start and stop. So at start kodi find a better resolution / refresh rate it switches, but if it does not find a better one it uses the 3840x2160 with 24 Hz the GUI is running right now at start.

LE12 behaves a little different and i had not the nerv to test it trough, but in LE12 you can change playback resolution in the settings for the playback (LE11 does not have that).

Now i go back an finish the movie to see if it really works the whole time.

orby you said here
RE: HDR on x86 Hardware
"audio at 24hz and gives random blips research looks to be the linux driver at fault for that"
can you point me to the right software that is the fault or even better a open bug?

That reads like the problem of this thread.

smp tested YCBCR444 patch: that does not change the problem.
Oh and another question how do i force 8 Bit or 10 Bit. I have no idea.

Edit: I verified the YCBCR444 on the Info screen of my Denon and there is now YCBCR444 and not RGB both with 12 bit

Edit 2: found libdrm proptest binary in my buildtree and copied it to the N100 and here is the output https://paste.libreelec.tv/elegant-cockatoo.log

Da Flex thanks for the info, but at the moment i dont feel going down that rabbit hole

smp How do i edit the edid and change "SCDC Present"? Nerver done that before. I just refreshed my edid collection https://sky42.libreelec.tv/testing/edid/. Kernel LE12 with your patch is building. Thanks.

Oh boy get kodi on Ubuntu 23.10 with PT working was lets say interessting.
So i have now kodi 20 from the team kodi ppa running in 2160p @ 23.976 Hz. That did take way longer then expected.
- fixed framerate because not switching with wayland
- no HDR
and HD Audio PT has the same problem

It is ridiculous how hard it is get PT running on Ubuntu even with the team kodi ppa.
I ended up with starting kodi with KODI_AE_SINK=ALSA kodi
What a colossal waste of time.

Any other helping suggestions?
If not i give up to get N100 running.
That is very sad !!!!
